YN27C internal combustion rock drill, YN30E internal combustion rock drill, gasoline rock drill 


 Overview: 
 Feature 
 1, do not replace the head internal parts, just move the handle as required, can be operating. 
 2, the use of aircraft operating convenience, the more time-saving, labor-saving, with chisel-speed, high efficiency characteristics. 
 3, it now stands at the class level of similar products, and similar parts completely interchangeable. 
 4, on the rocks perforated vertically downward, level up less than 45 ° vertical down the deepest drilling up to six meters. 
 5, host weight only 27 kg, and easy to carry, for the mountains, no power is particularly suitable for the region of the pressure equipment and temporary works of greater mobility. 
 6, both in the mountains, plains, and can work both in the heat of the 40 ° or 40 ° below zero cold regions, this machine has a wide range of adaptability. 
 Use 
 YN27C type internal combustion rock drill the bore of the mining, cement concrete pavement, asphalt and other split, broken, tamping shovel chisel function, widely used in mining, road building, quarrying, national defense projects.
